RE: [call for comments] voiD - vocabulary of interlinked datasets

Damian,

Thanks for your interest. I'll try to explain it better: voiD aims at
formalising Richard's nice 'bubble and arc' figure [1]. When we do this
we can say things like 'from e.g. riese.joanneum.at expect statistics
about Europe' AND we can describe the interlinking (such as riese links
to Geonames) as well. More formally:

:riese a void:Dataset ; 
       dc:subject <http://dbpedia.org/resource/Statistics> ;
       dc:subject <http://dbpedia.org/resource/Europe> .
              

:Geonames a void:Dataset ; 
       dc:subject
<http://dbpedia.org/resource/Location_%28geography%29> .

:riese-ls a void:Linkset ;
       void:from :riese ;
       void:to :Geonames .

You can imagine that we can now attach a bundle of properties to both
the dataset as well as to the linkset. We also suggest to use scovo [2]
for attaching stats about the dataset, such as found at sindice map [3]
(click on one of the sets) which is currently done manually.

Please let us know in case there are some more open issues.

Cheers,
	Michael
